The unknown number is 1/2 or 0.5.
ex: 4x+6=8
Answer:
x= 2
Step-by-step explanation:
y = 7 means it is parallel to the x axis . so the perpendicular line is to be parallel yo the y axis. .
so the equation is to be like x = c
but it is passing (2,13)
so the equation is
x= 2

Answer:
Step-by-step explanation:
convert mixed number to improper fractions
3
=
apply the fraction rule:
multiply the numbers
Given:
- Outer diameter = D = 80 ft
- Inner diameter = d = 40 ft
So,
Outer radius = R = D/2
=> R = (80 ft)/2
=> R = 40 ft
Inner radius = r = d/2
=> r = (40 ft)/2
=> r = 20 ft
Area of paved pathway = πR² - πr²
= π(R² - r²)
= π(R + r)(R - r)
= π(40 + 20)(40 - 20) ft²
= π(60)(20) ft²
= 3.14 * 1200 ft²
= 3768 ft²
